please solve the question then I send photo of this question then I tried to solve it

Answer 1

1) 1.1
2) 0.03
3) 0.4
4) 1.392

Answer 2

Given That Find Out Cube Roots Of The Following Decimals
1)1.331^(1/3)=(1331/1000)^(1/3)
=((11*11*11)/(10*10*10))^(1/3)
=(11/10)=1.1
2)0.000027^(1/3)=((27)/(10^6))^(1/3)
=3/10^2
=0.03
3)0.064^(1/3)=(64/1000)^(1/3)
=((4*4*4)/(10*10*10))^(1/3)
=(4/10)=0.4
4)2.7^(1/3)=(27/10)^(1/3)=((3*3*3)/10)^(1/3)
=(3/10^(1/3)) Take Nearest Number Which Has Perfect Cub Then Take 8 In Place Of 10
Then 2.7^(1/3)=(3/2)=1.5(approximate Value )
