Answer 10

To evaluate the expression, we follow the order of operations (also known as PEMDAS):

First, we perform the division: 64 ÷ 8 = 8.

Next, we subtract: 53 - 8 = 45.

Lastly, we add: 45 + 102 = 147.

Therefore, the value of the expression 53 - (64 ÷ 8) + 102 is 147.

Answer 11

To evaluate this expression, we follow the order of operations (PEMDAS):

First, we perform the exponentiation: 5^3 = 5 x 5 x 5 = 125.

Next, we perform the division: 64 ÷ 8 = 8.

Now, we perform the exponentiation: 10^2 = 10 x 10 = 100.

Finally, we substitute these values back into the original expression: 125 - 8 + 100 = 217.

Therefore, the value of the expression 5^3 − (64 ÷ 8) + 10^2 is 217.

Answer 12

To evaluate this expression, we follow the order of operations (PEMDAS):

First, we perform the exponentiation: 2^(-2) = 1/(2^2) = 1/4.

Next, we perform the multiplication inside the parentheses: (12 x 3) = 36.

Now, we substitute these values back into the expression: 1/4 x 36 - 5^3.

Then, we perform the exponentiation: 5^3 = 5 x 5 x 5 = 125.

Substituting it back: 1/4 x 36 - 125.

Finally, we perform the remaining multiplication and subtraction: 9 - 125 = -116.

Therefore, the value of the expression 2^(-2)⋅(12⋅3)−5^3 is -116.

Answer 13

To evaluate this expression, we need to simplify the exponentiation first.

First, we simplify the expression inside the parentheses: (3^3)^-1 = 27^(-1).

Next, we calculate the value of 27^(-1), which is equal to 1/27.

Therefore, the value of the expression 27 . ((3^3)^-1) is equal to 27 multiplied by 1/27, which simplifies to 1.

Thus, the expression evaluates to 1.

Answer 14

855,000,000,000 in scientific notation is 8.55 x 10^11.

Answer 15

To multiply numbers in scientific notation, we multiply the coefficients and add the exponents.

(5.91×10^−3)⋅(8.7×10^10) can be written as (5.91 * 8.7) * (10^-3 * 10^10).

The product of 5.91 and 8.7 is 51.297.

The product of 10^-3 and 10^10 is 10^(-3+10) which simplifies to10^7.

Therefore, (5.91×10^−3)⋅(8.7×10^10) can be written as 51.297 × 10^7 or in scientific notation as 5.1297 x 10^8.
