1)
LHS:
[tex] {a}^{4} \times {a}^{3} \times a \\ = {a}^{4 + 3 + 1} \\ = {a}^{7} [/tex]
LHS = RHS. So, the statement is true
2)
LHS:
[tex] {5}^{2} \times {3}^{4} \\ = 25 \times 81 \\ = {5}^{2} \times {9}^{2} \\ = {45}^{2} [/tex]
LHS not equal to RHS. So, the statement is false
3)
LHS:
[tex] {x}^{6} \times {x}^{0} \times {x}^{2} \times {x}^{3} \\ = {x}^{6 + 0 + 2 + 3} \\ = {x}^{11} [/tex]
LHS = RHS. So, the statement is true.
4)
LHS:
[tex]7 {m}^{2} \times 2m \times 4 {m}^{5} \\ = (7 \times 2 \times 4) {m}^{2 + 1 + 5} \\ = 56 {m}^{8} [/tex]
LHS = RHS. So, the statement is true.
