A^5b -a
= a* (a^(5b-1) -1) (distributive property)
Now try backwards:
a* (a^(5b-1) -1)
= a* a^(5b-1) -a
= a^1* a^(5b-1) -a
= a^(5b-1+1) -a
= a^(5b) -a (correct).
The final answer is a* (a^(5b-1) -1)~
The answer is: 4 because when you put the mixed number in an improper fraction it is 11/3 and 11 divided by 3= 3.67, so you will need to round it to the nearest whole number which is 4
Answer:
infinitely many solutions
Step-by-step explanation:
-x + 3y= -1
x - 3y =1
0=0
identity solution
The expression after factorisation is 4w⁴x² (7y⁷ + 3w⁵x⁶)
<h3>What is an Expression ?</h3>
An expression is defined as a mathematical statement consisting of variables , constants and mathematical operators.
The expression given is
28w⁴x²y⁷+12w⁹x⁸
Factors of the given expression will be the common terms in both the terms
w⁴x² is common in the variable term
The HCF of 28 and 12 is 4
4w⁴x² (7y⁷ + 3w⁵x⁶)
The expression after factorisation is 4w⁴x² (7y⁷ + 3w⁵x⁶)
