Answer:
a) 3⁴
b)7⁵
c)10²
d)5⁷
Step-by-step explanation:
a) 3²*3², add the exponents if multiplying(subtract if division)
b) add the other 7, cause 7⁴ is 7*7*7*7 and since you're doing another *7 just add a number to the exponent
c)10⁹/10⁷ is 9-7, and take that and use it as the exponent
d)since there is no exponent but it is basically the same as b, but switched. Instead of adding an exponent you take one away
