Hello there! How are you today?
5a^2 + 2b^3, solve when a = 4 and b = -4
To solve for this, we must replace "a" with 4, and "b" with -4.
I will set it up;
5(4^2) + 2(-4^3)
Simplify the parenthesis (PEMDAS).
5(16) + 2(-64)
Remove the parenthesis by multiplying them by the numbers to the outside of them.
5 x 16 = 80
2 x -64 = -128
We are now left with:
80 - 128
Simplify.
-48 is your final answer.
I hope this helps!
Tangent (angle) = 24 / 32
tangent (angle) = 3 / 4
arc tangent (3/4) = angle
angle = 36.87 Degrees
Answer:
-11,8 or 11,8........both are correct
When multiplying the same number with different exponents together you add the exponents.
7^6 ⋅ 7^5
6+5 = 11
Simplified becomes 7^11
1.3,,15,1,15,11,6,4,2,97
2.8,13,8,16,11,10,10,7,4,11
