Learning target I can write and evaluate numbers in exponent form using a base and a power, explain what each part stands for, and build one for a situation I have not seen before.

Remember6.3 Small Group · Group 2

The base is the factor and the exponent counts the factors, so switching them changes the value. Switching the base and the exponent changes the value. You can also write a number as a power.

Words: Exponent (Exponente)Base (Base)Power (Potencia)Evaluate (Evaluar)Repeated multiplication (Multiplicación repetida)
