Which expression is equivalent to 5^10 x 5^5?
5^2
5^5
5^15
5^50

Answer 1

Answer:

5^15

Step-by-step explanation:

5^5 is 3125, and 5^10 is 9765625. When multiplied, you get 30517578125. 5^5 is in the equation, so that couldn't be the answer. 5^50 is too big of a number, so that also wouldn't work. 5^2 is 25, and that would be too small. That leaves 5^15, which when calculated leads to 30517578125.

Answer 2

Answer:

5^15

Step-by-step explanation:

5^10 is equivalent to 9765625 and 5^5 is equivalent to 3125. 9765625x3125 is equal to 30517578125. We need to find the expression wich is equal to that number. It can't be 5^2 (25), 5^5 (3125), 5^50 (8.8817842e+34). The answer is 5^15 (30517578125)
