Question

`10^(0.48)=x,10^(0.10)=x,10^(0.70)=y` और `x^(z)=y^(2)` दिया गया है तो `z` किसके निकटतम है?
A. 1.45
B. 1.88
C. 2.9
D. 3.7

Answer 1

Correct Answer - C
`10^(0.48)=y`
`10^(0.70)=y`
and `x^(x)=y^(2)`
`:.(10^(0.48)^(z)=(10^(0.70)^(2))`
`implies 10^(0.48z)=10^(1.40)` (If `a^(x)=a^(y)`, if base equal power are equal `: (x=y)`
`z=140/48=35/12=2.9`
