Answer:
729/64
Step-by-step explanation:
= (3/2 a^-2b^2)^2
= 3^2 b^4 / 2^2 a^4
= 9b^4 / 4a^4
Plug in a = -2 and b = -3
= 9(-3)^4 / 4(-2)^4
= 9(81) / 4 (16)
= 729/64
The HCF is the highest common factor of two numbers.
By definition, if two numbers are coprime, they have no common factors other than 1.
So, the highest (and only) common factor of two coprime numbers is 1.

Step-by-step explanation:
40×4×4=640
b=20 h=4
using formula:
1/2×base×height
1/2×20×4=40
its says scale by factor 4:
b=80 h=16
using formula:
1/2×base×height
1/2×80×16=640
answer------>>>>640cm^2
