For this case we have the following expression: (-4a ^ -2 b ^ 4) / (8a ^ -6b ^ -3) We can rewrite the expression using properties of exponents. We have then: (-4/8) * ((a ^ (- 2 - (- 6))) (b ^ (4 - (- 3)))) Rewriting we have: (-2/4) * ((a ^ (- 2 + 6)) (b ^ (4 + 3))) (-1/2) * ((a ^ 4) (b ^ 7)) -1 / 2a ^ 4b ^ 7 Answer: The exponent of the variable b in Marina's solution should be 7
Step-by-step explanation: I think that because is you divide the 29 by 7.5 you get 3.86. Multiply the 11 by 3.86 and you get 42.46. If you round to the nearest tenth that would be 42.5
