Answer:
Step-by-step explanation:
Hi! Let me help you out.
__________________________
To simplify this expression, we should recall the 4th Property of Exponents.
[tex]\longmapsto\sf (ab)^m=a^m+b^m[/tex]
Meaning of the Formula
If we have a product raised to a power, we raise all the terms in this product to that power.
↪
Applying the Formula
The expression [tex]\sf (1.2m)^4[/tex] is a product of 1.2 and m; according to the formula above, we should raise both 1.2 and m to the power of 4.
[tex]\sf 1.2^4m^4[/tex]. Note that 1.2^4 can be simplified.
[tex]\sf 2.0736m^4[/tex]. Which is our final answer.
