Question

simplify (5^2-3^2)×(4/3)^-3
​

Answer 1

Answer:

Ans=2.528

Step-by-step explanation:

so the question is (3/4)*-2/(4/5)*-3*(3/5)*-2:

firstly convert the negative powers into positive:(4/3)*2/(5/4)*3*(5/3)*2

so it will be as:(16/9)/(64/125)*(25/9)

for making it easy make reciprocal of the second and change division into multiplication :(16/9*64/125)----16*64=1024 and 9*125=1125

divide both number now---->0.190

now multiply that with:0.190*25/9

=2.528

Answer 2

Answer:

27/4 = 6.75

Step-by-step explanation:

(5²-3²) x (4/3)⁻³

=(25-9) x (3/4)³    (Since, a⁻¹=1/a, so, (4/3)⁻³=(3/4)³

= 16 x 3³/4³

= 16 x 27/64

= 27/4 = 6.75
