Question

2. Scrie rezultatul calculului sub formă de putere: a) 2⁴⁹.2⁵³ b) 3⁵⁷:3²⁷ c) (5⁴) ²⁴ d). 2²⁹.3²⁹

Dau coroana​

Answer 1

$a) {2}^{49} \times {2}^{53} = {2}^{49 + 53} = {2}^{102} \\b) \: {3}^{57} \div {3}^{27} = {3}^{57 - 27} = {3}^{30} \\c) \: ({5}^{4})^{24} = {5}^{4 \times 24} = {5}^{96} \\d) \: {2}^{29} \times {3}^{29} = ({2 \times 3})^{29} = {6}^{29}$
