2)Reduza a uma só potência: a) 7^2times 7^6= b) 2^2times 2^4= c) 5times 5^3= d) 8^2times 8= e) 3^0times 3^0= f) 4^3times 4times 4^2= g) a^2times a^2times a^2= h) mtimes mtimes m^2= i) x^8cdot xcdot x= j) mcdot mcdot m=

a) $$7^{2}\times 7^{6} = 7^{2+6} = 7^{8}$$
b) $$2^{2}\times 2^{4} = 2^{2+4} = 2^{6}$$
c) $$5\times 5^{3} = 5^{1+3} = 5^{4}$$
d) $$8^{2}\times 8 = 8^{2+1} = 8^{3}$$
e) $$3^{0}\times 3^{0} = 3^{0+0} = 3^{0} = 1$$
f) $$4^{3}\times 4\times 4^{2} = 4^{3+1+2} = 4^{6}$$
g) $$a^{2}\times a^{2}\times a^{2} = a^{2+2+2} = a^{6}$$
h) $$m\times m\times m^{2} = m^{1+1+2} = m^{4}$$
i) $$x^{8}\cdot x\cdot x = x^{8+1+1} = x^{10}$$
j) $$m\cdot m\cdot m = m^{1+1+1} = m^{3}$$
