This one was pretty tough but Math way helped, you should try it out, it explains the problems so you can learn it. I got x = 0, 5
What you want to do is write the numbers with similar bases, and then you can cross the bases off. Like this:
25^x+2=125^3x+4
5^2(x+2)=5^3(3x+4)
Now you can cross the similar bases off.
2(x+2)=3(3x+4)
2x+4=9x+12
7x=-8
X=-8/7

Answer:
38
Step-by-step explanation:
Given that,
x = -4
f(x)=x² - 4x +6
so,
f(-4)= (-4)² - 4 . (-4) +6
=16 +16 +6
= 38

Answer:
621
Explanation:
143 + (96 + 8)(5) − 42
(96 + 8)(5)
= 520
143 + 520 - 42
= 663
663 - 42
= 621
