Question

(-21)*[(-4)+(-6)]=[(-21)*(-4)]+[(-21)*(-6)]​

Answer 1

Answer:

$3^x=9^x^+^5$

Explanation:

$5x-6=3x-8\\x^2-x-6=0\\x^4-5x^2+4=0\\\sqrt{x-1} -x=-7\\3x+1=4\\log_{2} (x+1) = log_{3}(27)\\= 3^x=9^x^+^5$

Answer 2

Explanation:Under distributive property

a*(b+c)=a*b+a*c

so,under distributive property they are equal
