Q. Which expressions are equivalent to 77⋅77⋅77⋅77⋅77⋅77?Choose 2 answers:(A) 7278(B) 76⋅71(C) (72)3(D) 72712
Understand original expression: Understand the original expression.The original expression is 7∗7∗7∗7∗7∗7, which is 7 multiplied by itself 6 times.This can be written in exponential form as 76.
Analyze option A: Analyze option A.Option A is (78)/(72). To determine if this is equivalent to 76, we can use the rule of exponents for division, which states that am/an=a(m−n).So, (78)/(72)=7(8−2)=76.This shows that option A is equivalent to the original expression.
Analyze option B: Analyze option B.Option B is 76×71. To determine if this is equivalent to 76, we can use the rule of exponents for multiplication, which states that am×an=am+n.So, 76×71=76+1=77.This shows that option B is not equivalent to the original expression.
Analyze option C: Analyze option C.Option C is (72)3. To determine if this is equivalent to 76, we can use the rule of exponents for powers, which states that (am)n=am∗n.So, (72)3=72∗3=76.This shows that option C is equivalent to the original expression.
Analyze option D: Analyze option D.Option D is (712)/(72). To determine if this is equivalent to 76, we can use the rule of exponents for division.So, (712)/(72)=7(12−2)=710.This shows that option D is not equivalent to the original expression.
