5^10x5^5

Answer 1

To simplify the expression, we can use the rule of exponentiation that states that when multiplying two numbers with the same base, we can add their exponents.

So, we have 5^10 multiplied by 5^5, which can be simplified as 5^(10+5) or 5^15.

Therefore, 5^10x5^5 = 5^15.

Answer 2

numerical equivalent of 9^9x9^-6

Answer 3

To simplify the expression, we can use the rule of exponentiation that states that when dividing two numbers with the same base, we can subtract their exponents.

We have 9^9 multiplied by 9^-6, which can be simplified as 9^(9-6) or 9^3.

Expanding further, we have 9^3 = 9 x 9 x 9 = 729.

Therefore, the numerical equivalent of 9^9x9^-6 is 729.
