Question

find m such that (-3)m multiply by x (-3)5 =(-3)7
b) simplify 25×t¯⁴/5¯³×10×t¯8,t ≠ 0​

Answer 1

Answer:

We know appropriate identity (x+y+z)2=x2+y2+z2+2xy+2yz+2xz.

=x2+(2y)2+(4z)2+2(x)(2y)+2(2y)(4z)+2(x)(4z)

=x2+4y2+16z2+4xy+16yz+8xz.

Answer 2

Answer:

Simplify:

5

−3×10×t −8

25×t −4

(t/=0
