Question

f(x)=10^x+7^x-14^x-5^x/1-cos4x at x=0

Answer 1

yes this can be possible by using algebraic formula

Answer 2

The function's value is ∞ (infinity).

given,

• F(x) = 10^x + 7^x - 14^x - 5^x/(1-cos4x)

at x=0,

•     F(0) = 10^0 + 7^0 - 14^0 - 5^0/(1-cos0)
• ⇒  F(0) = 1 + 1 - 1 - 1/(1-1)
• ⇒  F(0) = 2-1-1/0
• ⇒  F(0) = 1 - ∞ = ∞
