Question

Simplify the expression.

5+4⋅(8−6)2

Answer 1

To simplify the expression 5 + 4⋅(8−6)², we first need to solve the part inside the parentheses, (8−6), which is equal to 2.

So, the expression becomes 5 + 4⋅2².

Next, we need to evaluate the exponent, 2², which means 2 raised to the power of 2.

2² = 2 * 2 = 4.

Now, the expression becomes 5 + 4⋅4.

Next, we need to perform the multiplication operation, 4⋅4, which equals 16.

Now, the expression becomes 5 + 16.

Finally, we can now solve the addition operation, 5 + 16, which equals 21.

Therefore, the simplified expression is 21.
