(-3)^-3 x (-3)^-2 x (-3)^5​

Answer 1

Answer:

$Using the identity (m+a)(m+b)=m2+m(a+b)+ab.</p><p></p><p>Given, (2x+3)(2x+5) </p><p></p><p>We \: \: can \: apply \: the above \: identity \: by \: taking</p><p></p><p>m=2x, a=3 , b=5.</p><p></p><p>Hence, we get, </p><p></p><p>(2x+3)(2x+5)=(2x)2+(2x)(3+5)+(3×5)</p><p></p><p>⇒4x2+(2x)(8)+15</p><p></p><p>⇒4x2+16x+15</p><p></p><p></p><p>Hence, (2x+3)(2x+5)=4x2+16x+15.</p><p></p><p>$
