The image shows a section of a worksheet on exponents and roots, written in Catalan. It explains the concept of exponents, using the example $a \cdot a \cdot a \cdot a \cdot a = a^5$. The term "Es llegeix a elevat a la cinquena potència" translates to "It is read as 'a' raised to the fifth power."

The exercises ask to calculate the values of different expressions involving exponents:

1. $3^2$
2. $2^5$
3. $4^3$
4. $7^2$

Let's solve these:

1. $3^2$ = $3 \times 3 = 9$
2. $2^5$ = $2 \times 2 \times 2 \times 2 \times 2 = 32$
3. $4^3$ = $4 \times 4 \times 4 = 64$
4. $7^2$ = $7 \times 7 = 49$

Tip: Remember, when raising a number to a power, you're multiplying the base by itself as many times as the exponent indicates.
