How do you solve fractions step by step?
Subtract: 7/
8
- 4/
5
= 7 · 5/
8 · 5
- 4 · 8/
5 · 8
= 35/
40
- 32/
40
= 35 - 32/
40
= 3/
40
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(8, 5) = 40. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 5 = 40. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - seven eighths minus four fifths = three fortieths.
Exponentiation: the result of step No. 1 ^ 2 = 3/
40
^ 2 = 32/
402
= 9/
1600
In other words - three fortieths raised to the power of squared = nine one-thousand six-hundredths.

Answer:
(-7)^3 or -343
Step-by-step explanation:
[(-7) ^5 × (-7)^2] ÷ (-7)^4
=[(-7)^5+2] ÷ (-7)^4 (a^n × a^m = a^n+m)
=(-7)^7 ÷ (-7)^4
=(-7)^7-4 (a^n ÷ a^m = a^n-m)
=(-7)^3
=(-7)×(-7)×(-7)
= -343
