Question

solve step by step pls​

Answer 1

Answer:

•(3÷2)^7÷(3÷2)^9

=a^m÷a^n=(a)^m-n

therefore,(3÷2)^7-9=(3÷2)^-2

•(3÷2)^-2×(3÷2)^2

=a^m×a^n=(a)^m+n

therefore,(3÷2)^(-2)+2=(3÷2)^0=1

ANS-1

Answer 2

${( \frac{3}{2}) }^{7} \div {( \frac{3}{2}) }^{9} \times {( \frac{3}{2} )}^{2}$

According to BODMAS,We shall first do division and then multiplication.

${( \frac{3}{2}) }^{7 - 9} \times {( \frac{3}{2}) }^{2}$

${( \frac{3}{2}) }^{ - 2} \times {( \frac{3}{2}) }^{2}$

${( \frac{3}{2} )}^{ - 2 + 2}$

${( \frac{3}{2} )}^{ 0}$

$1$
