Simplify this can someone help please
2 answers:
We can simplify this in one of two ways:
1.
We multiply 81 * 81 * 81 * 3 * 3 * 3 * 3, and then figure out what factor of 3 that is.
2.
Or, the easier way, is to figure out what factor of 3 81 is and go from there.
Let's multiply by 3 until we get 81:
3 * 3 = 9
9 * 3 = 27
27 * 3 = 81
We've multiplied four 3's, so 81 is the same thing as writing 3^4, and we can simplify from there.
*remember! When multiplying exponents, you add them together. When putting an exponent to another exponent, we multiply
3^16 is our answer

Ans(1):
Given equation is f(x)=-1.5x+6
we can plug any number like x=0 and x=2 to find the f(x) also called y-value
plug x=0
f(x)=-1.5x+6 =-1.5*0+6 =0+6 =6
Hence first point is (0,6)
plug x=2
f(x)=-1.5x+6 =-1.5*2+6 =-3+6 =3
Hence first point is (2,3)
now we can graph both points then join them to get final graph of f(x)=-1.5x+6

Ans(2):
We can repeat exactly same process for f(x) = -1/2x-5.
So the final graph will look like attached picture:
