Question

यदि `sqrt(4096)=64` है तो `sqrt(40.96)+sqrt(0.4096)+sqrt(0.00496)+sqrt(0.00004096)` का मान दशमलव के दो अंकों तक क्या होगा?
A. `7.09`
B. `7.10`
C. `7.11`
D. `7.12`

Answer 1

Correct Answer - C
According to the question
`implies sqrt(40.96)+sqrt(0.4096)+sqrt(0.004096)+sqrt(0.00004096)`
`impliessqrt(4096/100)+sqrt(4096/10000)+sqrt(4096/1000000)+sqrt(4096/100000000)`
`implies 64/10+64/100+64/1000+64/10000`
`implies6.4+0.64+0.064+0.0064=7.11`
