Question

Any1 know the answer?

Answer 1

Don't agree with Diego.

Explanation:

When x=5,

`10 + {x}^(2) = 10 + {5}^(2) = 35 \\ {2}^(x) = {2}^(5) = 32`

35>32

When x=6,

`10 + {x}^(2) = 10 + {6}^(2) = 46 \\ {2}^(x) = {2}^(6) = 64`

Obviously, 46<64

When x=7,

`10 + {x}^(2) = 10 + {7}^(2) = 59 \\ {2}^(x) = {2}^(7) = 128`

Obviously, 59<128

Hence, conclusion

When

`x \geqslant 6`

`10 + {x}^(2) \leqslant {2}^(x)`
