You can rewrite the multiplication using properties of the exponents. We have that if the base is the same, the exponents are added. For this case, we have: Base = (- 4) Exponent = 1 Applying properties of exponents: (-4) (- 4) = ((- 4) ^ 1) ((- 4) ^ 1) = (- 4) ^ (1 + 1) = (- 4) ^ 2 answer: the expression is the same as (-4) ^ 2
Step-by-step explanation: The answer 20 is from 1400 divided by 70 making 20, if you take 1400 and turn it into 14 then 70 into 7 then divide 14 by 7 you get 2 now just add a zero to your answer.
