Answer:
use Pythagoras theorem formula
=
+ 
Step-by-step explanation:
=
+ 
= 576 + 324
= 900
C = 
C = 30
Does that make sense? :|
Step-by-step explanation:
3√8 is irrational number, and
2√18 is also irrational number
3√8 + 2√18 =
3×2√2 + 2×3√2 =
6√2 + 6√2 = 12√2
so, 12√2 is irrational number.
the correct answer is
A. the sum of two irrational numbers is irrational.
Answer:
5.4
Step-by-step explanation:
Answer:
B. 5
Step-by-step explanation:
Step 1: Rewrite the equation a bit
![\frac{7^\frac{3}{4}}{7^\frac{x}{8}}=\sqrt[8]{7}\\7^\frac{3}{4}^-^\frac{x}{8}=7^\frac{1}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B7%5E%5Cfrac%7B3%7D%7B4%7D%7D%7B7%5E%5Cfrac%7Bx%7D%7B8%7D%7D%3D%5Csqrt%5B8%5D%7B7%7D%5C%5C7%5E%5Cfrac%7B3%7D%7B4%7D%5E-%5E%5Cfrac%7Bx%7D%7B8%7D%3D7%5E%5Cfrac%7B1%7D%7B8%7D)
Step 2: Place a logarithm base 7 on both sides

Step 3: Solve for x

Neat exponent question :)
