△ABC is a right angled triangle and right angle at B

sinA=

, cosA=

⟹sinA+cosA=

BC+AB

[We know that sum of two sides of a triangle is greater than the third side]

⟹sinA+cosA>

Hence, sinA+cosA>1

Rewrite each expression in the form kkxxnn, where kk is a real number and nn is an integer. Assume x ≠ 0.

labwork [276]

Answer:

The expression will be $2x^5\times x^{10}=2x^{5+10}=2x^{15}$

Step-by-step explanation:

We have given the expression $2x^5\times x^{10}$

We have to write this expression in kkxxnn form , here kk is real number and nn is integer

We know the property of exponent that when two function are multiplied thn their exponent are added

So $2x^5\times x^{10}=2x^{5+10}=2x^{15}$

Here kk = 2 and nn = 15
