Answer 2

Answer:

Step-by-step explanation:

1. (2²+3²)*(1/2)²

=(4+9)/-*1/4=13/4

2.9*3ˣ=(27)²ˣ⁻³

3²3ˣ=3³*⁽²ˣ⁻³⁾

3²⁺ˣ=3⁶ˣ⁻⁹

so 2+x=6x-9

5x=11

x=11/5

3.   (27/64) ^-2/3

=(3³/2⁶)^-2/3

=(3/2²)^--3*2/3

=(3/4)⁻²

=(4/3)²

=16/9

4. 8^4/3+25^3/2-(1/27)^(-2/3)

=(2³)^4/3 +( 5²)^3/2-(1/3³)^-2/3

=2^4+5^3--(1/3)^-2

=16+125-3²

=141-9=132

****************************

5.

9⁰+9⁻¹-9⁻²+9^1/2-9^-1/2

=1+1/9-1/9²+√9-1/√9

=1+1/9-1/81+3-1/3

=Taking lcm it is 81

So= 1/81( 81+9-1+243-27)

=(216/81)

=24/9=8/3

6.

a^5*b^2/a^2*b^-3

=a^(5-2)*b^(2+3)

=a^3*b^5
