If you mean 4-2, that is, by definition, the same as 1 / 42.
36.5 is not an exponential expression! Its value is 36.536.5 is not an exponential expression! Its value is 36.536.5 is not an exponential expression! Its value is 36.536.5 is not an exponential expression! Its value is 36.5
no
42 = 4.2 × 101
For an exponential function: General equation of exponential decay is A(t)=A0e^-at The definition of a half-life is A(t)/A0=0.5, therefore: 0.5 = e^-at ln(0.5)=-at t= -ln(0.5)/a For exponential growth: A(t)=A0e^at Find out an expression to relate A(t) and A0 and you solve as above

It is: 73 = 343
Do you mean "equations involving exponential functions"? Yes,

I think the word you're looking for is "exponential". A linear expression is of the form ax + b whereas an exponential expression is of the form x^a + b.
depends on the question but an EXPONENTIAL EQUATION is in the for 2^x = 4 and you have to solve for x.
