Find true or false (\frac{2}{3} )^{-2} *(\frac{2}{3}) ^{-5} =(\frac{2}{3} )^{10}

Definition:

According to the law of exponents,exponents of numbers are added when the numbers are multiplied that is,

a^{m} *a^{n} =a^{m+n}

Step-by-step explanation:

If we solve ,the given equation it leads to as follows,

LHS=(\frac{2}{3} )^{-2} *(\frac{2}{3}) ^{-5} =(\frac{2}{3} )^{-2+(-5)}\\=(\frac{2}{3}) ^{-7} \\\\=(\frac{2}{3}) ^{-2-5} \\\neq RHS

Therefore,the given statement is false.
